Wilderness areas are federally-owned public lands managed by the federal government through four agencies, the Bureau of Land Management, Fish and Wildlife Service, Forest Service, and National Park Service. When the National Wilderness Preservation System started in 1964, only 54 wilderness areas were included. Since then, the system has grown nearly every year to include more than 800. The time component of this service is based on the year in which the wilderness was originally designated (additions may have occurred in subsequent years). Overall, however, only about 5% of the entire United States—an area slightly larger than the state of California— is protected as wilderness. Because Alaska contains just over half of America's wilderness, only about 2.7% of the contiguous United States—an area about the size of Minnesota—is protected as wilderness. To learn more about wilderness areas, visit Wilderness Connect, the authoritative source for wilderness information online. Wilderness Connect also publishes two other map resources:An interactive wilderness map allows visitors to search for and explore all wilderness areas in the United States. Fact-filled storymaps on the benefits of wilderness illustrate how wilderness protects values including clean water, wildlife habitat, nearby recreation, cultural sites and more. Although wilderness areas are federally-owned, some areas contain non-federal parcels within their boundaries. Non-federal lands within some wilderness areas are included as part of this feature dataset as a separate layer. Termed inholdings or edgeholdings, these lands are privately-owned or owned by local governments, state governments or Indigenous Nations. Hundreds of inholdings and edgeholdings exist across the wilderness system. Generally, however, they are small compared to the size of the wilderness itself. Since the rules and regulations that apply to wilderness areas do not apply to these non-federally-owned parcels, it is important for wilderness visitors to know their _location to avoid trespassing where access is not allowed. The owners of inholdings and edgeholdings can develop these parcels (as long as developments do not affect the character of the surrounding wilderness lands) and they retain special and limited access to them, sometimes, but not always, by motorized means.

This dataset includes the polygon features representing the spatial extent and boundaries of the Bureau of Land Management (BLM) National Landscape Conservation System (NLCS) Wilderness Areas (WLD), Wilderness Study Areas (WSA), and Other Related Lands with wilderness characteristics (LWC) or managed for wilderness characteristics (MWC).The data standard for these boundaries will assist in the management of all eleven designations within the NLCS. Particularly, NLCS data pertains to the following BLM groups and their purposes: Land Use Planners, GIS Specialists, NLCS team leads, BLM managers, and public stakeholder groups.As early as 1926, the earliest advocates of wilderness preservation had acknowledged the beauty and important ecological values of the desert lands under the BLM’s administration as candidates for wilderness protection. In 1964, Congress established the National Wilderness Preservation System and designated the first Wilderness Areas in passing the Wilderness Act. The uniquely American idea of wilderness has become an increasingly significant tool to ensure long-term protection of natural landscapes. Wilderness protects the habitat of numerous wildlife species and serves as a biodiversity bank for many species of plants and animals. Wilderness is also a source of clean water.The Federal Land Policy and Management Act of 1976 directed the BLM to inventory and study its roadless areas for wilderness characteristics. Here identified areas became WSAs. The establishment of a WSA served to identify areas for Congress to consider for addition to the National Wilderness Preservation System. To be designated as a WSA, an area must have the following characteristics: Size - roadless areas of at least 5,000 acres of public lands or of a manageable size; Naturalness - generally appears to have been affected primarily by the forces of nature; Opportunities - provides outstanding opportunities for solitude or primitive and unconfined types of recreation. In addition, WSAs often have special qualities such as ecological, geological, educational, historical, scientific and scenic values.In June 2000, the BLM responded to growing concern over the loss of open space by creating the NLCS. The NLCS brings into a single system some of the BLM's premier designations. The Wilderness Areas, WSAs, and Other Related Lands represent three of these eleven premier designations. By putting these lands into an organized system, the BLM hopes to increase public awareness of these areas' scientific, cultural, educational, ecological and other values.The BLM's management of all public lands included data within the NLCS is guided by the Federal Land Policy and Management Act (FLPMA). FLPMA ensures that many of BLM's traditional activities such as grazing and hunting, continue on the lands within the NLCS, provided these activities are consistent with the overall purpose of the area.A Wilderness is a special place where the earth and its community of life are essentially undisturbed; they retain a primeval character, without permanent improvements and generally appear to have been affected primarily by the forces of nature. BLM NLCS Other Related Lands are lands not in Wilderness or WSAs that have been determined to have wilderness character through inventory or land use planning. These lands fall into one of two categories. The first category are lands with "wilderness value and characteristics". These are inventoried areas not in Wilderness or WSAs that have been determined to meet the size, naturalness, and the outstanding solitude and/or the outstanding primitive and unconfined recreation criteria. The second category are "wilderness characteristic protection areas". These are former lands with "wilderness value and characteristics" where a plan decision has been made to protect them.To be designated as a WSA, an area must have the following characteristics: Size - roadless areas of at least 5,000 acres of public lands or of a manageable size; Naturalness - generally appears to have been affected primarily by the forces of nature; Opportunities - provides outstanding opportunities for solitude or primitive and unconfined types of recreation. In addition, WSAs often have special qualities such as ecological, geological, educational, historical, scientific and scenic values.There were forty-seven Wilderness Areas established under the Arizona Wilderness Act of 1984 and Arizona Desert Wilderness Act of 1990. These Acts require the BLM to file boundary legal descriptions and maps to Congress for each Wilderness Area. The standards, format, and language for the legal descriptions and boundary maps were developed during regular meetings of the NLCS Coordinator, GIS specialists and the Cadastral Surveyors. Guidance was provided from congressionally-required map and legal boundary descriptions detailed in the NLCS Designation Manual 6120 (March, 2010). All Arizona BLM Wilderness Area boundary legal descriptions and maps have been transmitted to Congress and certified by the Chief of Cadastral Survey and Arizona State Director. There should be no changes to Wilderness Boundary GIS data. Boundary changes can only be made through an amendment to the legal description and this would need to be sent back to Congress.

Feature Class for the BLM Wilderness Areas and BLM Other Related Lands data covered by the National Landscape Conservation System (NLCS) Data Standard. In particular, this feature class includes the polygon features representing the spatial extent and boundaries of the BLM National Landscape Conservation System (NLCS) Wilderness Areas. A Wilderness is a special place where the earth and its community of life are essentially undisturbed; they retain a primeval character, without permanent improvements and generally appear to have been affected primarily by the forces of nature.

The Federal Land Policy and Management Act of 1976 directed the Bureau to inventory and study its roadless areas for wilderness characteristics. To be designated as a Wilderness Study Area, an area has to have the following characteristics: Size - roadless areas of at least 5,000 acres of public lands or of a manageable size; Naturalness - generally appears to have been affected primarily by the forces of nature; Opportunities - provides outstanding opportunities for solitude or primitive and unconfined types of recreation. In addition, Wilderness Study Areas often have special qualities such as ecological, geological, educational, historical, scientific and scenic values. BLM National Landscape Conservation System (NLCS) Other Related Lands are lands not in Wilderness or Wilderness Study Areas that have been determined to have wilderness character through inventory or land use planning. These lands fall into one of two categories. The first category are lands with "wilderness value and characteristics". These are inventoried areas not in Wilderness or Wilderness Study Areas that have been determined to meet the size, naturalness, and the outstanding solitude and/or the outstanding primitive and unconfined recreation criteria. The second category are "wilderness characteristic protection areas". These are former lands with "wilderness value and characteristics" where a plan decision has been made to protect them. This dataset is a subset of the official national dataset, containing features and attributes intended for public release and has been optimized for online map service performance.

This dataset depicts those areas of Rocky Mountain National Park that were designated as wilderness pursuant to Public Law 111-11, Title I, Subtitle N., dated March 30, 2009. This dataset also depicts the portion of Indian Peaks Wilderness that was transferred to Rocky Mountain National Park pursuant to Public Law 96-560, Title I, Sec. 111, dated December 22, 1980. This dataset was used to create the maps entitled: * 'Rocky Mountain National Park Wilderness', numbered 121-101,335A and dated Jan. 2010; * 'Rocky Mountain National Park East Shore Trail Alignment', numbered 121-101,337A and dated Jan. 2010. This dataset was used to create the maps within the document entitled: * 'Rocky Mountain National Park Wilderness Boundary Descriptions', numbered 121-101,336A, and dated Jan. 2010. Pursuant to Public Law No: 111-11, two maps and a detailed boundary description document were prepared for the Secretary of the Interior, for his inspection and approval, and for submission to the Committee of Energy and Natural Resources of the Senate and the Committee on Natural Resources of the House of Representatives. The finalized map and wilderness boundary descriptions were prepared 'as soon as practicable' after P.L. 111-11 was published. The detailed descriptions of the wilderness boundary underwent a thorough in-Park review to check for language consistency and clarity before being submitted to the Secretary. This finalized GIS dataset and the detailed descriptions of the wilderness boundary were made available as public domain data after being submitted to the Secretary and the aforementioned Congressional Committees in April 2010. This dataset depicts that approximately 95% of Rocky Mountain National Park has been designated as wilderness. The legislation stated that "approximately 249,339 acres of land in the Park, as generally depicted on the map" were designated as wilderness. After the final configuration of the East Shore Trail Alignment was established, this finalized dataset depicts 249,125 acres designated as wilderness in 2009. Rocky Mountain National Park Wilderness: 249,125 acres Existing Indian Peaks Wilderness within RMNP: 2,960 acres --------------------------- TOTAL Wilderness within RMNP: 252,085 acres Percent of RMNP that is Wilderness: 94.8% The official and legal TOTAL acreage figure for Rocky Mountain National Park is 265,828.41 acres. This has been determined by summing up all the legal descriptions of all the parcels that make up Rocky Mountain National Park. This figure varies slightly (less than one half of one percent) from the figure calculated for this data by the GIS software. Use the official acreage of 265,828.41 acres in any documents referencing the size of Rocky Mountain National Park.

Athough MassGIS has served trails information from the Department of Conservation and Recreation (DCR) for many years, this new Trails layer is MassGIS’ first attempt at a statewide, multi-sourced dataset. This layer was created from two primary sources, DCR Trails and the Metropolitan Area Planning Council’s (MAPC) Trailmap. Additionally, a few other trail networks were added from OpenStreetMap (OSM), municipalities, and conservation organizations, but the amount of information from these sources is relatively small.This trails dataset was created for use in the State 9-1-1 Department’s mapping application Response Assist and is intended to assist telecommunicators with lost hikers as well as potentially responding to emergencies within remote areas. Because the layer is primarily being used by 9-1-1, it was decided to focus on those trails found in wilderness areas and used as hiking trails. This resulted in the omission of many arcs from the source data. Examples of these include cart paths on golf courses, the network of paved paths on school campuses, sidewalks, and many other arcs that could functionally serve as trails but were in relatively open and developed areas.Updated with linework from OpenStreetMap in summer 2023 and published on November 14, 2023.See full metadata.Map service also available.

This data layer depicts the Designated Wilderness and Proposed Wilderness placed upon the lands and waters administered by the U.S. Fish and Wildlife Service (USFWS) in North America, U.S. Trust Territories and Possessions. Only the U.S. Congress can designate Wilderness. The Service establishes Proposed Wilderness administratively. The primary source for this information is the USFWS Wilderness program.

WLD_CHAR_POLY: This theme represents the results of an inventory of wilderness characteristics found, or not found, on BLM lands in Oregon and Washington. This data set shows the polygons for areas found to possess wilderness characteristics, plus polygons for those areas that were intensively inventoried and found to not meet minimum wilderness criteria. All BLM lands outside of designated Wilderness Areas and Wilderness Study Areas are periodically evaluated for wilderness characteristics based on meeting minimum criteria for size, naturalness and outstanding opportunities for solitude or primitive and unconfined recreation. Where such inventories have been updated, those BLM lands not depicted by polygons were deemed to clearly lack wilderness characteristics in an initial scan of size and roadlessness to determine areas warranting more intensive inventory.

This shapefile contains boundaries for Designated Wilderness in Chiricahua National Monument, Arizona as of 2021. This dataset is based on the map identified in the law enacting wilderness for the park and the 850 acre wilderness land addition in 1984. The date of the original enactment map is 10/20/1976. The Congressionally Designated Wilderness is based on careful study of roadless areas, public hearings, and written responses. This dataset has been revised from the map to adjust buffers along roads and utilities, account for changes to the boundary and land status, and reflect more accurate measurement available through new GIS technology. Land added to the boundary after the 1976 enactment, except as noted, has not been studied for wilderness. In May of 1984, Congress added adjacent U.S. Forest Service land that was made wilderness at the same time. This dataset identifies 10,629 acres within Chiricahua National Monument as Designated Wilderness. This dataset identifies 0 acres within Chiricahua National Monument as Potential Wilderness (2 acres in 1977). The dataset did not contain the 2 acres because the map identified in the law enacting wilderness for the park did not show its location, however, the 2 acres still exist. This map was updated February 2021 using NAD 83 zone 12N and 40 feet contours created from a 10m DEM in conjunction with the 1976 map.
